Party Of The Week: Clash of the Titans bash ushers in the summer season

Former Bond girl Gemma Arterton, who plays a spiritual guide in the 3D epic Clash of the Titans, was spectacularly busy on Monday night. After signing autographs on the red carpet for the film's world premiere in London, she dashed off to perform in her West End show, The Little Dog Laughed, at the Garrick Theatre down the road. She missed out on watching the film but returned in time for the after party, held at the chic restaurant and bar, Aqua London, housed in the former Dickens & Jones department store on Regent Street.

The film's director, Louis Leterrier, who previously directed The Incredible Hulk and Transporter 2, joined cast members Alexa Davalos, Jane March, Mads Mikkelsen, Skins alumnus Nicholas Hoult, Jason Flemyng and Luke Treadaway to celebrate the premiere, ahead of the film's release today. They mingled with other guests, including the actor Alfie Allen, fashion designer Ozwald Boateng and the actor Andy Serkis.

Avatar star Sam Worthington, who trained six hours a day for two months to get in shape to play the film's hero, Perseus, son of Zeus, arrived with his girlfriend, Natalie Mark. But Ralph Fiennes, who plays Hades, god of the underworld, was nowhere to be seen. He is, apparently, busy filming and starring in his directorial debut, Shakespeare's tragedy Coriolanus, in Siberia. Or to put it another way, he's swapped Ancient Greece for the Roman Empire.

Sipping on a cocktail after the screening, Worthington said: "We're trying to kick it off with a bang. This is a fun, boisterous movie. It shouldn't be taken too seriously. It's a popcorn film. This is the start of the summer blockbusters."
